Use of Chemicals for Local Technologies !….

Farmers can not actually be blamed for this as they have not enough idea about the harmful effects of these chemicals on human and ecological health !

They are only ‘concerned’ about the ‘effects’ which are instant and constant ! Because they are poor

Use of Chemicals for Local Technologies !

Use of Chemicals for Local Technologies !

Farmers generally use local materials to make local indigenous technologies(ITKs). Nowadays chemicals are handy to the farmers. Because they use a lot of chemicals as pesticides, herbicide, hormones etc.

So the farmers may be tempted to use these chemicals to evolve indigenous technologies. And these technologies can be potentially harmful to all.

Some Company people who are not fully knowing the Agrochemical Science are helping the farmers secretly to do this !

Unlike before, the locally available materials have changed. The farmers now have a range of agrochemicals from Multi-National Companies(MNCs) in their houses for crop production and protection ! So they can now use these to “improvise” and “design” technologies which can be very harmful !

HYVs Precede Chemicals ?

High Yielding Varieties Precede the Use of Chemicals in Agriculture ?

High Yielding Varieties in the 1960s is a major development in agriculture. The dwarf varieties replaced the tall varieties. The dwarf varieties can carry higher grain loads without lodging. But they consume higher amount of chemical fertilizers. The farmers use only Nitrogenous fertilizers, namely Urea, which makes the crops visibly luxuriant and at the same time succulent.

HYVs are meant to consume higher dose of chemical fertilizers to yield more. But in the field level it is seen that the farmers are tempted to use only Urea as the source of Nitrogenous fertilizer and remain satisfied with their crop growth which are deep green and sappy making the crops attractive to insect and disease pests. They are reluctant to use basic other fertilizers dose of Phosphate and Potash fertilizers which makes the crops hardy, resistant and capable of more yield bearing, because these two types of fertilizers have less of visible impact on crops.
